“…The transmission spectra of FES were obtained using Specord M-40 and Specord 75 IR spectrophotometers. The line width ∆H of films was measured by the "magnetic gup" method [7] in which the area of localization of measurements is 0,4 mm. The saturation magnetization 4πMs of films was measured using a vibrating magnetometer [8].…”

“…For these purposes is required a material with a certain set of parameters: the ferrite layer thickness (d), saturation magnetization (4πMS), the anisotropy field, the FMR line width ∆Н etc. This is achieved by selecting the optimal chemical composition of the charge and the technological process for growing high quality films with a minimum number of defects [4].…”

The growth of iron-yttrium garnet Y3Fe5O12 (YIG) films with of 1...15 μm thicknesses on single-crystal substrates of gallium-gadolinium garnet Gd3Ga5O12 (GGG) was carried out using the method of liquid phase epitaxy (LPE). The influence of the composition and mass of the charge, the temperature regimes, the rates of movement and the substrate rotation on the films parameters were studied. The layered structure caused by the heterogeneity of the chemical composition in the film thickness was determined and studied The dependence of the degree impurity of Pb2+ and Pt4+ ions in YIG films and their influence on the ferromagnetic resonance (FMR) line width ∆H on the films growth conditions was investigated. It’s shown that in order to obtain by the LPE method the series of defect-free films with low magnetic losses and reproducible parameters, it’s necessary to use melt-solutions of large mass (6...12 kg) and apply their additional mixing during the growth process.

“…For the epitaxial growing, an automated installation was used, i.e., technological operations were controlled by a computer. The temperature in the furnace was maintained with an accuracy of ±0.1 K. The FMR line width in La : YIG films was measured, by using a non-destructive method in a frequency interval of 1.2-4.0 GHz [6]. The saturation magnetization of the films was monitored with the help of a vibration magnetometer [7].…”

Basic principles of growing the thick (35-60 m) single-crystalline La-substituted yttriumiron garnet (Y3− La Fe5O12, La : YIG) films with reproducible parameters have been formulated. La : YIG films are grown on gallium-gadolinium garnet (Gd3Ga5O12) substrates from a supercooled melt-solution (MS) consisting of Y2O3, La2O3, and Fe2O3 oxides and the PbO-B2O3 solvent. In order to minimize the implantation of Pb 2 + ions into the films, which degrades the film quality, the epitaxy has to be performed at high temperatures and a low MS supercooling. It is found that, in order to maintain a constant growth rate of La : YIG films with reproducible parameters, a large MS mass (10-16 kg) has to be used, and the MS temperature has to be permanently lowered at a rate of 0.042 K/min.
